This minimally invasive surgical technique has many advantage; small incision,minimal tissue dissection,preserving the integrity of both facet and ligament-muscle complex and do not cause spinal instability. Operation time is similar to standard technique laminectomy. Approximate duration is one hour for one level.
Intervention code [1] 255820 0
Treatment: Surgery
Comparator / control treatment
Laminectomy for decompression of lumbar spinal stenosis. This is standard technique for treatment of LSS. In this technique wide exposure and decompresion may cause spinal instability and lower clinical success rate.
Control group
Active
